Help, NullPointerException when trying to login jabber.org

Hi, I am new to this, trying to create my a client app to connect to jabber.org and login, here is my code (pretty much from doc), I used the same username and password logged in using Pandion client successfully, I don’t know what I am missing here (by the way I can’t get the enhanced debugger to show up even if I included smackx-debug.jar in the classpath, only the lite one)? I also tried using ConnectionConfiguration same result.

thanks a lot!


XMPPConnection.DEBUG_ENABLED = true;

XMPPConnection connection = new XMPPConnection(“jabber.org”);

connection.connect();

System.err.println("==connected");

connection.login(“myusername”, “mypassword”);

System.err.println("==login");

ChatManager chatmanager = connection.getChatManager();

I got following exception:

==connected
java.lang.NullPointerException

at org.jivesoftware.smack.PacketReader$1.run(PacketReader.java:76)

I downloaded and looked at the source code, it seems the response from sc.evaluateChallenge() call returns null… in code SASLMechanism.java line 152, is that a bug?

I am using smack 3.1.0, java 1.6.0_13, my ISP is road runner, I can login fine using Pandion.

anyone can help here? or any developer can see if this is a bug?

thanks!
